Hi, we are seeing this test fail on our internal linux build bot. I built/ran
your latest change r310537 and here is the test result:
/home/dyung/src/upstream/llvm_clean/tools/clang/test/Driver/openmp-offload.c:722:23:
error: expected string not found in input

Executing the run line from line 719 of the file at r310537 produces the
following output:
